JEWELERS PLIERS.

Specification of Letters Patent.

Patented Nov. 2'7, 1906.

Application filed July 23, 1906. Serial No. 327,383-

To (ti/Z whom, it may concern:

Be it known that I, ELZIE C. CHAMBERLIN, a citizen of the United States,residing at Denison, in the county of Crawford and State of Iowa, haveinvented a new and useful J ewelers Pliers, of which the following is aspeci fication.

This invention relates to jewelers pliers such as are adaptedparticularly-for use in sptting stones in rings or other pieces of jewery.

Difficulty is often experienced in setting a relatively soft stone orother ornamentsuch, for example, as an imitation pearlfor the reasonthat the pressure exerted upon the prongs for forcing them into contactwith the periphery of the stone sometimes crushes or mars the latter.Furthermore, in addition to the danger of crushing a soft stone in theoperation of setting the same, another disadvantage attending the use ofordinary prongs such as are cast or otherwise formed upon the ring whenit is manufactured is that they increase the cost of manufacture, andtherefore tend frequently to decrease the profit.

With the foregoing disadvantages in View the object of the presentinvention is to provide a strong, simple, durable, inexpensive, andthoroughly-eflicient form of jewelers pliers which are equipped with arotary adjustable setting-tool adapted when properly operated to gougeor cut a plurality of integral slivers of gold from an ordinary plaingold ring in such manner that the setting tool can be easily manipulatedto bend the slivers of gold over into contact with the periphery of thejewel, so as to act as prongs for setting the jewel without danger ofmarring or crushing the same and without the necessity of providing aring which in the course of its manufacture has been previously formedwith setting-prongs.

Afurther object of the invention is to cause the grooves which areproduced in the ring by the setting-tool to present a neat, smooth, andfinished appearance.

With the foregoing and other objects in. view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of invention herein disclosed can be made within the scope ofthe following claims without departing from the spirit of the inventionor sacrificing any of its advantages.

In the accompanying drawings, forming part of this specification, Figure1 is a perspective View of a pair of pliers constructed in accordancewith the invention. Fig. 2 is an enlarged detail view showing the jawsand the setting-tool operating upon a ring for setting a stone therein,said figure being partly in section. Fig. 3 is an enlarged detail Viewof the conical or bell-shaped portion of the setting-tool.

Like reference-numerals indicate corresponding parts in the differentfigures of the drawings.

The jewelers pliers of this invention preferably comprise a lower jaw 1and an upper jaw 2. The jaws 1 and 2 are provided with handles 3 and 4,which cross each other in the usual manner and are pivotally connected,as indicated at 5. The lower jaw 1 preferably is formed with a curvedupper or inner face 6, so that it can be engaged with the inner face ofa ring without scratching or marring the same. The outer corner of thejaw 1 preferably is beveled, as indicated at 7, to avoid the formationof a sharp edge, which might have a tendency to injure a piece ofjewelry if brought in contact therewith. The upper jaw 2 is designed toreceive a rotary adjustable setting-tool, which in the embodiment ofinvention illustrated-consists of a screw 8, extending through athreaded opening in the jaw 2 and having across its upper end a groove 9to receive a small screw-driver for rotating and adjusting thesettingtool or screw. The inner end of the setting tool or screw 8 isdressed down, so as to be approximately conical in shape, as indicatedat 10, or, in other words, to resemble a bell, in that the conicalportion 10 is slightly dished or curved inward intermediate its ends andflared outward at its outer portion or large end, as shown. The conicalor bell-shaped portion 10 preferably is filed or otherwise out at itsinner end to form a fiat inclined or beveled face 11. The setting toolor screw 8 is set through the jaw 2 at an incline or angle of aboutfifteen degrees, as shown. The outer end of the jaw 2 preferably isrounded, as indicated at 12, to avoid the formation of sharp corners,which might tend to scratch a piece of jewelry.

Constructed as described the manner of using the improved pliers is asfollows: A settingsuch, for example, as a half or semithe setting-tool 8can be forced into the gold spherical imitation pearlis placed againstthe periphery of the ring in which it is desired to set the same. Thelower jaw 1 of the pliers is then fitted inside the ring, so as to bearagainst the'same adjacent the stone setting. The setting tool or screw 8is then rotated so that its flat inclined face 11 will be disposedtoward the stone, with the pointed inner end of the tool 8 resting uponthe gold a short distance from the setting. delicate pressure upon thehandles 8 and 4 in such manner as to cut a small integral sliver of goldtherefrom, after which by carefully manipulating the pliers the goldsliver or prong can be upset or bent over onto the periphery of thestone setting. The pliers will then be moved slightly, so that thesetting-tool 8 will engage thegold ring at a slight distance fromanother part of the periphery of the setting. Each time the pliers aremoved to out another sliver of gold the setting-tool 8' willbe slightlyrotated in the always to be disposed toward the stone setting. Bycarefully manipulating the pliers the slivers of gold can be producedand bent i over onto the periphery of the setting in such a delicatemanner that any danger of crush- 1 ing the soft setting is almostentirely avoided. It will be obvious that the advantage in using asetting-tool 8 which is rotatable upon the jaw 2 is that it can bereadily turned so that the fiat inclined face 11 will be always jdisposed toward the setting and in this way 1 the necessity of turningthe handles of the l pliers or of changing the position of the ring 1with respect to the device will be avoided.

The advantage of using an adjustable setting-tool 8 is that it can beemployed upon rings or pieces of jewelry of different thicknesses bysimply adjusting it longitudinally within the jaw 2.

It is found in practice that by passing the tool8 through the aw 2 at anincline of about l fifteen degrees the pliers can be more readily l Byexerting manipulated for cutting the prongs in the gold, as described.

The advantage in using the conical or bell-- shaped portion 10 upon theinner end'of the construction as well as thoroughly efficient inoperation.

What I claim is- 1. A pair of jewelers pliers comprising a pair ofjaws,'and a rotary adjustable settingtool extendingthrough one of saidjaws and having a pointed inner end and a fiat inclined face disposed atan angle to the axis of the 1 tool and approximately at right angles tothe adjacent jaw, for substantially the purposes set forth.

2. A'pair of jewelers pliers comprising a pair of'jaws, and asetting-tool consisting of a jaw 2 so as to cause its flat inclined face11 screw extending through one of said jaws at an incline and having anapproximately conioal end formed with a flatface inclined to the axis ofthe screw.

3. A pair of jewelers pliers comprising a pair of jaws having handles,one of said jaws being formed with a curved inner face and a beveledouter corner and the other of said I jaws, having a curved outer face,and a setting-tool consisting of a screw extending through said jaw atan angle of approximately fifteen degrees, said setting-tool having anapproximately conical or bell-shaped inner end formed with a flatinclined face, for

. substantially the purposes set forth.

In testimony that I claim the foregoing as 1 my own I have heretoaflixed my signature in the presence of two witnesses.
